The AD8469 is a fast comparator fabricated on XFCB2, an Analog Devices, Inc., proprietary process. This comparator is exceptionally versatile and easy to use. Features include an input range from VEE − 0.2 V to VCC + 0.2 V, low noise, TTL- and CMOS-compatible output drivers, adjustable hysteresis control, and a shutdown input. The device offers a 40 ns propagation delay driving a 15 pF load with 10 mV overdrive on 500 μA typical supply current.
A flexible power supply scheme allows the device to operate from a single +2.5 V positive supply with a −0.2 V to +2.7 V input signal range up to a +5.5 V positive supply with a −0.2 V to +5.7 V input signal range.
The TTL-/CMOS-compatible output stage is designed to drive up to 15 pF with full rated timing specifications and to degrade in a graceful and linear fashion as additional capacitance is added. The input stage of the comparator offers robust protection against large input overdrive, and the outputs do not phase reverse when the valid input signal range is exceeded.
The AD8469 is available in an 8-lead MSOP package and features a shutdown pin and hysteresis control. It is fully specified over an operating temperature range of −40°C to +125°C.
